WAxBoM,

paratus of the class in which each is .sup-- ported on a movable base (preferably a wheeled truck) and carries a horizontally projecting kerf cutting mechanism which is capable of movement horizontally and is adapted to operate while supported on the base or truck. In using a minin of this type it is customary to lity a single track along the center of the room or entry being cut. The mining mechanism or apparatus is then moved forward along this track to a point near the face and use is made of the cutting mechanism thereof to out a kerf extending across the face from one side of the room to the other. The cut ting mechanism remains supported on the truck while the cutting is being carried on. By my invention I have provided an ap paratus in which the cutting mechanism is movable not only transversely across the front of the machine (preferably angularly about a fixed vertical axis), but also translatively outward and inward away' from and toward the central parts of the truck; and I have provided power operated means for moving the .cutting mechanism horizontally (in this case radially) relatively to the base frame to feed the mechanism to its work. The outer limit of radial movement is controllable and can be varied for difi'er ent angular positions. For this reason the machine can be used to cut kerfs having outlines other than semi-circular.

I have shown an apparatus which comprises a mining machine of the breast type supported on a turntable which is mounted on a wheeled truck; but it will be understood that there can be wide variation as concerns the specific form of cutting mechanism used and as concerns the means for States, residing at apparatus driving and controlling it. I have shown the mining machine as removable from the truck so as to be capable of operation at points separate from the truck; but it will be understood that the invention, in some respects, is not limited to an apparatus com prising a removable or separable complete mining machine.

In the apparatus shown the cuttin mech anism is supported at a relatively high elevation, so as to cut a kerf a considerable distance above the mine floor. A relatively.

high kerf is referable under many circumstances, but it will be understood that the invention is not limited as concerns the hei ht of the kerf.

he principal object of the invention is to provide a mining'apparatus of the type specified having a cutting mechanism which is movable horizontally both angularly and translatively, and which is referably adapted for the cutting of kerfs non-circular in outline.

A further object of the invention the provision of a mining apparatus comprising a truck and a mining machine adapted to operate while supported on the truck, and

also to be uided for movement ofi the truck for operation independently thereof.

Another object of the invention is the provision of mining apparatus comprising a coal cutting machine and a supporting and transporting truck adapted to support the machine to out in relatively elevated planes while the machine is upon the truck and also to guide the machine for movement oil the truck, either downward for operation upon the bottom proper of the mine, .or at a higherelevation, as for operation upon a bench. A further object is to provide an apparatus by means of which a series of cuts can be made radially from a center. A still further object is to provide a truck so constructed that a mining machine upon it can be readily turned end for end as desired. Another object is to provide, in combination with a truck having means for reversing the position of the mining machine, mechanism ion mining machine is in either position. Stillother objects will be apparent from the following specification.

Of the accompanying drawings which illustrate one embodiment of my invention- Figure 1 is a plan view showin the truck with the mining machine remove Fig. 2 is a si mining machine removed.

Fig. 3 is a fragmentary sectioiial view taken along the line 3'3 of Fig. 1.

Fig. 4 is a plan view showing the mining machine upon the truck.

Fig. 5 is a rear view showing the mining machine upon the truck.

Fig. 6 is a dia rammatic view indicating one way in whic an apparatus embodying my invention may be used.

Referring to the drawings, 1 represents as a whole the main base frame of the truck. This frame is preferably made u of rolled steel sections such as channels. he frame has side members 1*, 1, and transverse end members 1', 1 The frame 1 is mounted by means of suitable bearings on transverse rotatable axles 2, 2, to which are secured track wheels 3, 3. At each end of each axle 2 there is a sprocket wheel 4. The uses of these sprocket wheels will be referred to hereinafter.

For purposes of illustration I have shown on the truck a breast mining machine of standard construction which need not be described in detail. The machine shown is similar to that described in the patent to E. R. Merrill, No.-798,108, dated August 28, 1905, and reference can be had to that patent for details not herein shown. The mining machine comprises a carriage or cutter frame 27 and mounted upon this cutter frame is a cutting mechanism in the form of an endless cutter chain 28 carrying cutters 29. The connections between the cutter frame 27 and the main truck frame 1 are such that the cutter frame is movable horizontally either angularly or bodily outward and inward. When the cutter frame is a part of a standard breast mining machine such as is here shown, it is mounted on a bed frame 25 in such a way that it is longitudinally movable with respect thereto. The side parts of the bed frame constitute a guide which permits the cutter frame to have translative horizontal movements, but prevents relative angular movements.

In the construction shown, the bed frame 25 rests upon a supporting frame 5, which is rotatably mounted on the main truck frame 1 by means of a suitable turntable. This turntable, as shown in the drawings, is movably supported on a ring 6 which is preferably angle-shaped in cross section with its horizontal flange extending outward from the top of its vertical flange. The ring is mounted between the side members 1, 1, of

e view of the truck withthe the frame 1 and between two cross members 7, 7, which extend transversely between the .side members. The vertical flange of the ring engages the vertical webs of the channel sections and the horizontal flange rests upon and is secured to the top flanges of the channel sections. The turn-table, in the construction illustrated, is in the form of a ring 8 which also is angle-shaped in cross section and constructed with its horizontal flange extending outward from the top of its vertical flange. The ring 8 is of such size that its vertical flange will lie just within the vertical flange of the ring 6 to be held thereby against lateral movement, rotar movement, however, being freely permitted. Interposed between the horizontal flange of the ring 8 and the horizontal flange of the ring 6 are a number of rollers 9, 9, which are held in place and guided by. rings 10, 10.

It 15 upon the ring 8 that the frame 5 before referred to is mounted. This frame 5 comprises two bars 11, 11, which are preferably angle-shaped in cross-section with their vertical flanges extending upward at the outer sides. These bars 11, 11 are parallel throughout a part of their length; but at one end of the frame they diverge in order to be adapted for receiving the mining machine proper. The bars 11, 11 are connected at their ends by cross pieces 11 and 11".

The bed frame 25 of the mining machine comprises the bottom shoes 25 which characterize the machine of the Merrill patent above mentioned and which are adapted to slidably engage the angle bars 11 of the truck (as indicated in Fig. 5) as well as to rest upon and slide over the mine floor when the machine is used independently of the truck.

The turntable and the support therefor constitute a pivot device about Which the cutter frame 27 is permitted to swing. This pivot device has a vertical axis, which in the construction shown is fixed ,with respect to the truck frame. It will be observed that this pivot device together with the aforesaid guide on the bed frame 27 serves at each position of transverse adjustment of the cutter frame to hold the said frame in a definite angular relation to the base frame. By this construction the cutter frame is held against indefinite movements relatively to the base frame. as the angular position is definitely fixed for each transversely adjusted position.

Near each end of the main truck frame 1 is a transverse bar or beam 12 which is preferably channel-shaped in cross section. The beams 12 are of such a height that they can engage the under surfaces of the bars 11, 11

of the frame 5 to give additional support to the frame. It is obvious that these beams manner 12, 12 prevent either end of the frame from swinging downward in case of uneven loadend a sprocket wheel mg. Near one end of each of the bars 11 is alatch 13 which is so located that it can, when the frame 5 is in central position, engage a suitable aperture 13 in the top flange of one or the other of the beams 12, 12 to lock the frame 5 against rotary movement.

At one end of the frame 5', preferably at the end at which the bars 11 diverge, there are secured two hinges 14, 14, for the attachment of jacks 15, 15. These acks are adjustable in length by means of hand nuts- 16, 16, and by being extended by. meansof the nuts can .be forced into engagement with the floor of the mine to lock the frame 5 .againstlateral movement in either direction.

Additional means for holding the machine to its work is provided in the form of Jack.

26 which is mounted on the bed frame of the mining machine. This jack can engage the roof or other wall of the mine and is inclined so as to effectively resist the-reaction due to the engagement of the cutters with the coal as they advance across the end of the cutter frame. As the jack 26 is attached tothe bed frame of the mining machine it is adapted to perform the function described, both when the mining machlne is operated on the truck and when it is operated separately therefrom on the floor of the mine.

\ At the end of theframe 5 opposite to that at which the bars 11 diverge there is mounted a transverse rotatable shaft 17 which carrise at its inner end near the center of the frame a bevel gear wheel 18 and at its outer alinement with the sprocket wheels 4, 4 at the'corresponding ends of the axles 2, 2. 20 is a bevel gear wheel meshing with the bevel gear wheel 18. This wheel is secured to a suitable longitudinal shaft mounted in the bearin 21 on the frame 5. At the other end of thls shaft is a clutch element 22 adapted to be engaged by a similar clutch element on the mining machine to be described.

As the ends of the truck frame 1 are similar, and as the turntable is centrally located with respect to the axles, the frame 5 can be turned end for end on' the truck whenever this is found necessary or convenient. As

each end of each axle is provided with a sprocket wheel 4 it is always possible to con- L clutch 41 is 19 in longitudinal the sprocket wheels 4, 4 at the side of the truck opposite; to that on which the sprocket wheel 19 is located.

For driving the cutter chain 28 there is mounted upon the carriage or cutter frame 27'. an electric motor 30 which is connected to the chain by means of suitable gearing 31. Mechanism is provided for automatically feeding the carriage or cutter frame backward and forward on the bed frame. This mechanism comprises a transverse rotatable shaft which is provided at its end with pin-J ions 32, 32 which mesh with racks 33, 33

seoured to the bed frame. Mounted upon the transverse shaft are worms or spiral gear wheels 34 and 35 with which mesh worms 36 and 37 on parallel longitudinal shafts. These parallel longitudinal shafts carry at their forward ends worm wheels 38 and 39 which mesh with a worm 40 on the vertical driving shaft on the gearing 31. The wheels- 34 and 35 are loosely mounted on the transverse feedshaft and either of them can be secured to it by means of the clutch 41. The

provided with an operating lever 42. By means of this'lever either of the worm or spiral gearwheels 34 or 35 can be connected with the transverse feed shaft. When one-wheel is connected the carriage or cutter frame will be advanced relatively slowly and when the other wheel is connectedthe carriage or cutter frame will be retracted relatively rapidly.

The longitudinal shaft which carries the worm or spiral gear 36 also carries a clutch element 43 which is adapted to engage the clutch element 22 on the truck when the machine is in the proper position. It will be obvious that when the clutch elements are engaged, power can be transmitted from the motor to the mining machine through the shafts and gearing which have been described to drive the wheels of the truck.

The mining machine can be locked in place on the frame 5 by means of the devices indicated in 47, 47.

When the invention is embodied in an' apparatus of the form shown in the drawings I prefer to follow the method of operation which is indicated in Fig. 6.

A track 44 is laid down the center of the room and the machine is run into the room by its own power. When the machine has reached the proper place the wheels are; blocked preferably by means of the device indicated in Fig. 2 which comprises two blocks 45, 45 adapted to engagethe wheels. Between these blocks 45, 45 is an adjustable strut 46 by means of which the blocks can be forced apart and into firm engagement with the wheels and the track. The chain 23 is then removed and the frame 5 unlocked from the main truck frame 1. The frame 5 with the mining machine is then swung to one side, and the machine is jacked in position in the usual way, use being also made of the jacks, 15, 15 and 26 which engage the mine floor and roof, respectively, to prevent the frame 5 from swinging. The mining machine is then started and a horizontal laterally extending kerf is cut into the coal. .Aft r the kerf is cut the cutter or carriage frame is retracted, the jacks are loosened and the machine is swung into position for another cut. The machine is secured in this second position and the mining machine is then started, a second cut into the coal being made. In Fi 6 the full lines show the machine comp etin one cut, and the dotted lines show it comp eting another cut. This operation is repeated, the machine being swung on the turntable, until a complete kerfsemi-circular in outline has been cut into the coal. Then the machine is removed from the room by its own power and the coal is broken down in the usual way. It will be noted that by the use of this apparatus, the room has a semi-cylindrical face instead of a plane face. This, however, is not a disadvantage but, on the contrary, is a distinct advantage, as loading of the coal is made easier. I

It will be understood that the apparatus can be used in ways differing from the way above described and it is not limited to the cutting of a complete semi-circular series of radial cuts. As the cutting mechanism is movable radiall away from and toward the central parts 0 the truck, andas the outer limit of cutting is readily controllable for each angular position by means of the lever 42 the radial distances from the central part of the truck to the outer edge of the kerf at different points, circumferentially separated, can be varied as may be desired to cut a kerf having an outline other than a simple semicircular outline, such as that indicated in Fig. 6. In this respect an apparatus embodying my invention, has marked advantage over earlier mechanism which were adapted only for cutting arcuate kerfs.

By means of an apparatus embodying my invention a distinct saving of time and labor is effected. I am enabled not only to save the time ordinarily required for unloading the machine from the truck and reloading it, but also to save a large part of the time usually consumed in moving the machine from one position to another. By means of the turntable mounting, the machine after the jacks have been loosened can be very easily and quickly moved and rapidly placed in exactly the desired position. The time between cuts is in this way very materially reduced. If at any time it a is desired to use the mining machine in the usual way apart from the truck, the machine can be easily removed after removing the locking devices 47, 47. In removing the mining machine its shoe bars 25 slide, as

frame having longitudinally stated above, upon the ide rails 11 of the truck and, when the mac ine is off the truck, said shoe bars slidably support it for operation on the mine floor. It will be seen that the guide rails 11 of the truck, constituting as they do a part of the rotatable supporting frame, are adapted to discharge the machine in any desired angular direction, or When loading'to receive it from any desired angular direction; and by reason of the elevated position of the supporting frame of the truck it is especially adapted to discharge the mining machine in various angular directions upon a bench.

I have already noted that my invention in some respects is not limited to the type of mining machine employed, and it may be observed in that connection that the manner of handling the apparatus, whether the machine is operating while on the truck or separate therefrom, will depend in some measure upon the type of mining machine employed.

I do not herein claim as a part of my present invention the mining machine truck alone, as that is made the subject of my copending application for mining machine trucks, Serial No. 871,712, filed November 12, 1914, as a division of this application.
